GATE.

SPECIFICATION forming part of Letters Patent No. 224,100, dated February3, 1880. Application led October 31, 1879.

To all whom it may concern:

Be it known that l, JUNIUS C. MENDEN- HALL, of Plainfield, iu the countyof Hendricks and State of Indiana, have invented certain new and usefulImprovements in Gates; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanyingdrawings, which form part'of thisspecilication.

My invention Irelates to an improvement in selt' opening and closinggates; and it consists in the arrangement and combination of parts thatwill be more fully described hereinafter, whereby a cheap, simple, andeffective gate is pro duced. j

Figure l `is a side elevation of my invention. Fig. 2 is a plan viewofthe saine. Fig. 3 is a `detail view, and Fig. 4.- is a side view ofthe gate as closed. j

4 c represents the gate, which may be of any desired construction; b,the post upon which the gate is hinged; d, the post against which thegate latches, and c the post upon which the gate is held while open. t

At a suitable distance beyond the gate, on both sides, is placed adouble crank, j', for the wheels ot' the vehicle to strike against foropening and closing the gate, and each of these cranks has one ot' itsends to project inside ot' the hollow post e, where an arm, g, issecured to it. To .each end of the arni is secured a wire or rope, h,which extends up to two ot' the ends ot' a double arm, i, which ispivoted in the top of the post. To the other two ends ot' the double armare fastened the two wires y', which extend across over the top ofthepost b'to the double arm in` the other hollow post e.

The two posts c and 1the one b are made quite tall, so that the wires jwill be raised high above the reach of all stock andmaliciously-inclined persons. t

Vhere the posts are low, stock .are constantly getting their headscaught in the wires, and not only injuring the animals themselves, butbreaking the mechanism of the gate.

That portion of the top hinge of the gate which is secured to the postbtconsists of the bent rod l, the top of which extends above the Atopvof the post, and is braced in position by means of the plate m, whichis secured to the post. Fitting down upon the top of this rod is a cap,n, which passes down through the brace-plate, and which has theleverosecured to its upper end. To the rear short end of the lever issecured 'one of the operating-wires j, and to the front end of the leveris fastened the spring p. The front end of the spring is attached to thelever q, which projects froni the top of the post r of the gate, andserves to pull the gate suddenly open or shut.

The levero begins to move some time before the mechanism for looseningthe latch, and hence stretches the springuntil the latch is moved7 whenthe gate iiies suddenly open or shut. The tension of this spring is soregulated that it exerts just enough pressure on the gate when it isstretched to throw the gate from one post to the other and canse thelatch to catch. This spring does away with all need ofiucliuiug the gateto either side so as to cause it to swing openv or shut.

Also, secured to the cap nis a cam, s, which bears against the side of aroller, t, on top of the lever u, which is pivoted to the inside of thepost r. To the lower end ot this lever is connected the latch 'o bymeans of a wire, w, so that when the cam, in turning with the cap,forces the upper end ot' the lever inward, the latch is drawn back so asto release the gate and allow the spring-to throw it open or shut. Also,connected to the latch is the handlever m, so that the latch can beoperated by persons on horseback wit-hout the trouble of dismounting.

Having claim- Thecombination of the cranks f, having their inner' endsextending into the post-s c, and provided with the levers g, with thec'on nections h, spiders i, located in the tops ot the posts c, andwires j, whereby the wires are raised above the reach `ot' animals,substan-Y tially as shown.

In testimony that l claim the foregoing I have hereunto set my hand this27th day of October, 1879.
